isn't it a sign of racism in this country when outsiders are blamed for everything?
Not at all. When a massive percentage of terrorists in the world today happen to be Muslim and often Arab as well, that fear is well based, I think. I wouldn't say treating every Muslim and Arab as a potential terrorist - but groups of these people should be watched more carefully, as they have proven themselves to have some... ill-sentiments towards the west, and various... unlawful actions these sentiments have led them to do.

Yes, it's not a very nice thing to categorise people and watch them like they're out to get you... but these are dire times, and we're not talking about some mass killings or mass banishment of Muslims within Britain and\or other western nations - simply being on the lookout, watching these communities more carefully because of their tendency to produce terrorist and support terrorist activities.
